SPECIFICATION forming part of Letters Patent No. 380,501, dated April 3, 1888.

Application filed J uly 19, 1887.

To atl whom may sonneri/tf Beit known that I, GEORGE D. LODEE, of Covington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Vindow-Sash Fasteners, of which the following is a specificaion.

My invention relates to that class of win- .dow-fastenings one part of which is attached at the top of the lower sash and the other part to the bottom of the upper sash.

The object of my invention is to provide novel means for locking the sashes when closed.

The invention consists in the features of construction and combination of devices hereinafter described and claimed, reference being made to the accompanying drawings, in which Figure 1 is a perspective view of my im provement in position for use. Fig. 2 is a sectional elevation showing the lower and upper sashes locked. Fig. 3 is a similar section showing the position of the parts when the lower sash is being raised. Fig. 4 is a similar view showing the position of parts when the locking-tumbler is pushed back in position for raising the lower sash. Fig. 5 is a section on line :c Fig. 3. Fig. 6 is a front elevation of the face-plate. Fig. 7 is a detail view of the trigger.

1 represents the lower sash-frame; 2, the upper sash.

3 represents a block secured to the lower sash and provided with a trippinglug, 4, and a guard, 5. The block is preferably attached to the sash by the screw 6.

7 represents the face-plate of the boX or shell, which is inserted into the sash-frame, as shown in Figs. 2, 3, 4, and 5.

S'reprcsents the top of the box, to which is attached the upper end of a spring, 9.

10 represents a pin projecting out from one side of the box.

11 represents the locking-tumbler. It is provided with a slot to receive the pin 10, and it loosely rests against the vibrating spring 9, which normally pushes the locking-tumbler 11 outward, as shown in Fig. 2, the lower end normally resting upon the face of the trippinglug 4 and the guard 5 preventing it from being thrown out too far.

Serial No.' 244,752. (No model.)

The face-plate 7 of the box or shell is provided with a vertical slot, 13, for the projection of the tumbler 11, and a slot, 14, is provided of a less width than the slot 13, to provide the shoulders l2. In the lower end of the box or shell is pivoted, by pivot 17, the

inner end, 16, of a trigger, 15, having its outer end adapted to move vertically in the contracted slot 14, and provided on its upper face with a lug, 18, and normally raised by the spring 19, as in Fig. 3. The lug 18 ou the trigger l5 is adapted to engage the front of the lower end of the tumbler 11, when the latter is pushed inward and moved downward on the pin 10. This downward movement of the tumbler throws its lower end behind the shoulders 12, which thereby hold the tumbler in its retracted position under tension of the spring 9, as shown in Fig. 3,where the sashes are unlocked.

The parts being in the position shown in Figs. 1 and 2, the sashes are loclred together, and if it is desired to raise the lower sash or drop the upper sash the tumbler 11 is pushed back by the finger, compressing spring 9. The weight of the tumbler will then cause it to drop on the pin 10 until the lower end of the tumbler falls behind the shoulders 12, which hold the tumbler retracted,while at the same time the trigger is caused to engage, by its lug 18, with the lower front end of the tumbler, Fig. 3. When the parts are in this position, Fig. 4, if the lower sash be raised, the tripping-lng 4 is moved away from the trigger 15. The spring 19 raises thelattenwhich raises the tumbler 11 until its lower end is above the plane of the shoulders 12. The tumbler in the meantime is held retracted by the lug on the trigger until the sash is lowered and the tripping-lug strikes the trigger and releases the tumbler 11, which is at once projected by the spring 9, and it assumes a post tion over the trippng-lu g 4.

It will be observed that by means of the tumbler having a slot to engage the pin 1() the tumbler can both swing inward and rise and fall, and by this construction, in connection with the shoulders 12, behind which the tumbler passes when it drops, the tumbler can be raised and automatically set when the lower sash is raised and the trigger elevated by the tially, of the plate 7, having the slots 13 and 14 I5 and shoulders 12, the longitudinally-moving tumbler 11, spring 9, trigger 15, spring 19, and the tripping-lug 4, substantially as specified.

3. The combination, in a window-fastening, of the faceplate 7, having the side iianges, 20, With the swinging tumbler 11 and its trigger 15, substantially as described.

In testimony whereof I have hereunto set my hand.

GEORGE D. LODER.
